FBI warns QR code phishing used in North Korean cyber spying
NEWYou can now listen to Fox News articles!
The Federal Bureau of Investigation has issued a warning about a growing cyber threat that turns everyday QR codes into spying tools.
According to the bureau, a North Korean government-sponsored hacking group is using a tactic known as quishing to target people in the United States.
The goal is simple. Trick you into scanning a QR code that sends you to a malicious website. From there, attackers can steal login credentials, install malware or quietly collect device data.

What quishing is and why it works
Quishing is short for QR code phishing. Instead of clicking a suspicious link in an email, the victim scans a QR code that hides the real destination. QR codes themselves are harmless. The danger lies in the link embedded inside them. Once scanned, the link can redirect users to fake login pages, malware downloads or tracking sites. Because QR codes feel familiar and fast, many people scan them without thinking twice. That split second of trust is exactly what attackers rely on.
Who is behind the attacks
The FBI says the activity is tied to a hacking group known as Kimsuky. The group has operated for years as a cyber espionage arm for North Korea. What is new is the delivery method. According to the FBI, the QR code-based attacks began in May 2025. In one example, attackers posed as a foreign policy advisor and emailed a think tank leader with a QR code that linked to a fake questionnaire. Scanning the code sent the victim to a malicious site designed to harvest information.
What happens after you scan the QR code
Once a victim lands on one of these sites, several things can happen. Some pages prompt users to download files that contain malware. Others mimic mobile login portals for popular services such as Okta, Microsoft 365 or VPN services. Even if no form is filled out, the site can still collect device details. That includes IP address, operating system, browser type and approximate location. Over time, that data helps attackers build intelligence profiles on their targets.
Why QR code phishing attacks are highly targeted
The FBI describes these campaigns as spear phishing rather than mass spam. That means the emails are crafted for specific individuals. The language context and sender details are tailored to look relevant and credible. When an email feels personal, people are more likely to trust it. That is why these attacks are especially dangerous for professionals, researchers, executives and anyone working in policy or technology.
Why QR code phishing threats are growing
QR codes are everywhere now. Restaurants, parking meters, event tickets and ads all rely on them. As their use grows, so does the opportunity for abuse. Attackers know people are conditioned to scan without hesitation. That makes caution more important than ever.
Ways to stay safe from QR code phishing
The FBI says one of the best defenses against quishing is slowing down. QR codes remove the visual clues people rely on, so a few extra checks can make a big difference.
1) Be cautious with unexpected QR codes
Treat QR codes like links in emails. If you did not expect it, do not scan it. QR codes sent by email, text or messaging apps are a common entry point for quishing attacks. Criminals rely on curiosity and urgency to push you into scanning without thinking.
2) Verify the source before scanning
Always confirm who sent the QR code. If a message claims to come from a coworker, vendor or organization, reach out through a separate channel before scanning. A quick call or direct message can stop a phishing attempt cold.

3) Never enter logins after scanning a QR code
QR code phishing often leads to fake mobile login pages. Attackers mimic sign-in screens for email, VPNs and cloud services to steal usernames and passwords. If a QR code takes you to a login page, close it and visit the site manually instead.
4) Inspect the website URL carefully
Once a QR code opens a page, check the address bar. Look for misspellings, extra words or unfamiliar domain endings. A strange URL is often the only warning sign that the site is malicious.
5) Use strong antivirus software for QR-based threats
Strong antivirus software adds an extra layer of protection against quishing. Security tools can block known phishing sites, stop malicious downloads and warn you before harmful pages load. This is especially important on mobile devices, where QR codes are most often scanned.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

6) Use a data removal service to limit exposure
Some quishing sites collect device and location data even if you do nothing. A data removal service helps reduce how much personal information is publicly available online. That makes it harder for attackers to target you with convincing spear phishing emails that include QR codes.
While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.

7) Avoid QR code downloads entirely
Do not download files from QR code links unless you are absolutely certain they are safe. Malware delivered through QR codes can quietly install spyware or remote access tools without obvious warning signs.

Kurt’s key takeaways
QR codes are convenient, but convenience can lower defenses. As this FBI warning shows, attackers are evolving and using familiar tools in dangerous ways. A moment of verification can prevent weeks or months of damage.

A rogue AI led to a serious security incident at Meta
For almost two hours last week, Meta employees had unauthorized access to company and user data thanks to an AI agent that gave an employee inaccurate technical advice, as previously reported by The Information. Meta spokesperson Tracy Clayton said in a statement to The Verge that “no user data was mishandled” during the incident.
A Meta engineer was using an internal AI agent, which Clayton described as “similar in nature to OpenClaw within a secure development environment,” to analyze a technical question another employee posted on an internal company forum. But the agent also independently publicly replied to the question after analyzing it, without getting approval first. The reply was only meant to be shown to the employee who requested it, not posted publicly.
An employee then acted on the AI’s advice, which “provided inaccurate information” that led to a “SEV1” level security incident, the second-highest severity rating Meta uses. The incident temporarily allowed employees to access sensitive data they were not authorized to view, but the issue has since been resolved.
According to Clayton, the AI agent involved didn’t take any technical action itself, beyond posting inaccurate technical advice, something a human could have also done. A human, however, might have done further testing and made a more complete judgment call before sharing the information — and it’s not clear whether the employee who originally prompted the answer planned to post it publicly.
“The employee interacting with the system was fully aware that they were communicating with an automated bot. This was indicated by a disclaimer noted in the footer and by the employee’s own reply on that thread,” Clayton commented to The Verge. “The agent took no action aside from providing a response to a question. Had the engineer that acted on that known better, or did other checks, this would have been avoided.”
Last month, an AI agent from open source platform OpenClaw went more directly rogue at Meta when an employee asked it to sort through emails in her inbox, deleting emails without permission. The whole idea behind agents like OpenClaw is that they can take action on their own, but like any other AI model, they don’t always interpret prompts and instructions correctly or give accurate responses, a fact Meta employees have now discovered twice.

Phishing scam exploits Apple Mail ‘trusted sender’ label
NEWYou can now listen to Fox News articles!
Phishing emails are getting more convincing every day. Scammers copy the look of trusted brands and rely on urgency to get you to click before you think. But sometimes the most misleading part of a scam is not the email itself. It is the signal your own email app gives you.
A CyberGuy reader recently sent us a screenshot of an email that looked suspicious but included something surprising at the top. Apple Mail displayed a banner that said, “This message was sent from a trusted sender.” At first glance, that message feels reassuring. Many people would assume the email must be legitimate. The reader sent the screenshot with the subject line “Another sneaky trick.” In the image, Apple Mail labels the message as coming from a trusted sender even though the email itself shows several signs of a phishing scam.
Here is the catch. That label comes from Apple Mail itself, not from Apple and not from a system verifying the email. In other words, a phishing email can still appear trusted. Understanding how this happens can help you avoid handing your Apple ID or other personal information to scammers.

Why Apple Mail may label a phishing email as a trusted sender
Apple Mail automatically adds the trusted sender banner in certain situations. It usually appears when the email address looks familiar to your device. For example, Apple Mail may display the banner if:
- The sender’s address is saved in your Contacts
- You have replied to that email address before
- The address appears in previous email conversations
The feature is designed to help you quickly recognize people you communicate with often. It is meant as a convenience signal, not a security verification. That distinction is important.
Warning signs of a fake Apple account email
Phishing emails often copy the look of real Apple notifications. The goal is to create urgency so the victim clicks before thinking. The email in the screenshot contains several classic warning signs.
Generic greeting
The message begins with “Dear user” instead of addressing the recipient by name. Legitimate account emails typically reference your name or Apple ID information.
Slightly incorrect branding
The email references “Cloud+ subscription.” Apple’s real service is called iCloud+. Small branding mistakes often appear in phishing campaigns.
Urgent scare tactics
The message warns that personal data could be permanently removed from cloud storage. Fear and urgency are common tools in phishing scams.
Payment problems tied to account threats
Scammers often claim a subscription payment failed and your account is at risk. The goal is to push victims to click a link and enter login details. Apple does not send emails threatening immediate deletion of iCloud data because of a billing issue.
Why the Apple Mail trusted sender banner can be misleading
Because the banner relies on familiarity, scammers can sometimes exploit it. Cybercriminals often spoof real email addresses so their messages appear to come from someone you know. If that address matches a contact or previous message history, Apple Mail may still mark it as trusted.
REAL APPLE SUPPORT EMAILS USED IN NEW PHISHING SCAM
That can create a false sense of safety. The banner simply reflects your email history. It does not confirm the sender’s identity or verify that the message actually came from Apple or any legitimate company. In some cases, that visual signal can make a phishing email look more believable than it really is.

Ways to stay safe from Apple phishing emails
Phishing emails continue to evolve, but a few simple habits can greatly reduce your risk.
1) Avoid clicking links in account warning emails
If you receive a notice about your Apple account, open your browser and go directly to Apple’s official website instead of using the email link.
2) Use strong antivirus software
Strong antivirus software can help detect malicious links, suspicious downloads, and phishing pages before they reach your device. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com
3) Use a data removal service
Scammers often gather personal information from data broker websites to make phishing emails look more convincing. Removing your data from these sites reduces the information criminals can use to target you. Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting Cyberguy.com.
4) Check your Apple account settings directly
You can verify subscriptions by opening Settings on your device, tapping your Apple ID and selecting Subscriptions.
5) Look closely at branding and wording
Misspelled product names, unusual formatting, and generic greetings often reveal a phishing email.
6) Enable two-factor authentication
Two-factor authentication (2FA) adds another layer of protection, even if someone manages to steal your password.

Kurt’s key takeaways
Email apps often try to help by identifying messages that appear familiar. Unfortunately, scammers understand how those systems work. The trusted sender banner in Apple Mail reflects your contact history. It does not confirm that the message came from Apple or any legitimate company. That means one simple habit still offers the best protection. Pause before clicking any urgent account warning. Because in the world of phishing scams, the messages that look the most convincing are often the most dangerous.
If your email app told you a message was trusted, would you still double-check before clicking? Let us know by writing to us at Cyberguy.com.
